Process for foliar fungicide treatment and fungicide composition for implementing the process

Abstract

The present invention relates to a process for the control of fungal disease of plants by applying to the leaves of the plants: a) 2-(4-chlorobenzylidene)-5,5-diemthyl-1-(1H-1, 2,4-triazol-1-ylmethyl)-1-cyclopentanol; b) one or more fungicides suitable for protecting against the said fungal diseases and to compositions which may be used in the process.

We claim: 
     
       1. A process for the treatment of a plant suffering from, or protection of a plant subject to, fungal diseases which comprises applying to the leaves of the plant a fungicidal and non-phytotoxic amount of a component (a) 2-(4-chlorobenzylidene)-5,5-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)-1-cyclopentanol and a component (b) at least one dicarboximide derivative, wherein the weight ratio of component (a) to component (b) is from 0.0003:1 to 3,000:1. 
     
     
       2. A process for the treatment Of a plant suffering from, or protection of a plant subject to, fungal diseases which comprises applying to the leaves of the plant a fungicidal and non-phytotoxic amount of a fungicidal composition comprising a component (a) 2-(4-chlorobenzylidene)-5,5-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)-1-cyclopentanol, a component (b) at least one dicarboximide derivative and an agriculturally acceptable carrier wherein the weight ratio of component (a) to component (b) is from 0.0003:1 to 3,000:1. 
     
     
       3. The process according to claim 1, wherein the fungal diseases are diseases of cereals, vines, market garden crops, arboricultural crops, tropical crops, rice, maize, beet or rape. 
     
     
       4. The process according to claim 2, wherein the fungal diseases are diseases of cereals, vines, market garden crops, arboricultural crops, tropical crops, rice, maize, beet or rape. 
     
     
       5. The process according to claim 1, wherein the weight ratio of component (a) to component (b) is from 0.001:1 to 1,000:1. 
     
     
       6. The process according to claim 2, wherein the weight ratio of component (a) to component (b) is 0.001:1 to 1,000:1. 
     
     
       7. The process according to claim 1, wherein the amount of component (a) and component (b) applied is 0.002 to 1 kg/ha. 
     
     
       8. The process according to claim 2, wherein the amount of component (a) and component (b) applied is 0.002 to 1 kg/ha. 
     
     
       9. The process according to claim 7, wherein the amount applied is 10 to 600 g/ha. 
     
     
       10. The process according to claim 8, wherein the amount applied is 10 to 600 g/ha. 
     
     
       11. The process according to claim 1, wherein the dicarboximide derivative is selected from the group consisting of captan, folpel, captafol, iprodione, procymidone and vinclozolin. 
     
     
       12. The process according to claim 11, wherein the dicarboximide derivative is iprodione. 
     
     
       13. The process according to claim 2, wherein the dicarboximide derivative is selected from the group consisting of captan, folpel, captafol, iprodione, procymidone and vinclozolin. 
     
     
       14. The process according to claim 13, wherein the dicarboximide derivative is iprodione. 
     
     
       15. The process according to claim 2, wherein the fungicidal composition further comprises an agriculturally suitable surface-active agent. 
     
     
       16. A composition for the treatment of a plant suffering from, or protection of a plant subject to, fungal diseases comprising a component (a) 2-(4-chlorobenzylidene)-5, 5-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)-1-cyclopentanol, a component (b) at least one dicarboximide derivative and an agriculturally suitable inert carrier, wherein the weight ratio of component (a) to component (b) is from 0,0003:1 to 3,000:1 
     
     
       17. The composition according to claim 16, wherein the weight ratio of component (a) to component (b) is from 0.001:1 to 1,000:1. 
     
     
       18. The composition according to claim 16, wherein the dicarboximide derivative is selected from the group consisting of captan, folpel, captafol, iprodione, procymidone and vinclozolin. 
     
     
       19. The composition according to claim 18, wherein the dicarboximide derivative is iprodione. 
     
     
       20. The composition according to claim 16 further comprising an agriculturally suitable surface-active agent.
